They have greatly improved the cleanliness of drinking water in homes and public places. The design and installation of household water purifiers are constantly innovating to meet the needs and space layout of different families. The common installation forms of drinking water machines on the market mainly include under-cabinet type, wall-mounted type and vertical type.

[0034] Referring to Figure 1 , a schematic diagram of a wall-mounted water purifier 100 in an embodiment of the present application is shown. In some embodiments, the wall-mounted water purifier 100 is provided on an external mounting surface, which is generally a vertically arranged wall surface, cabinet surface, etc. The wall-mounted water purifier 100 includes a waterway system 10 and a housing 20. The housing 20 is used to provide support and protection for the waterway system 10, and to provide a mounting position for the waterway system 10.

[0035] Referring to Figures 2 to 5 The waterway system 10 is used to realize the filtering and purifying function of the wall-mounted water purifier 100. Specifically, the waterway system 10 comprises a pre-filter 11, a water inlet electromagnetic valve 12, a booster pump 13, a reverse osmosis filter 14 and a post-filter 16 connected in sequence.

[0036] The pre-filter 11 is connected to the raw water inlet end 1, and the post-filter 16 is connected to the pure water outlet end 2. The pre-filter 11 is used to preliminarily filter the large-particle impurities in the raw water entering the raw water inlet end 1, such as mud, rust, suspended solids and the like, to prevent the large-particle impurities from causing blockage or damage to the reverse osmosis filter 14. The water inlet electromagnetic valve 12 is used to control the raw water filtered by the pre-filter 11 to enter the reverse osmosis filter 14, and the booster pump 13 is used to increase the water pressure to meet the pressure required by reverse osmosis.

[0037] The reverse osmosis filter 14 is used to deeply purify the raw water filtered by the pre-filter 11. Generally, the reverse osmosis filter 14 is provided with a reverse osmosis membrane. The raw water is forced to pass through the reverse osmosis membrane, so that most of the pollutants are blocked on one side of the membrane, and only pure water flows out of the membrane. The reverse osmosis membrane can remove most of the dissolved salts, heavy metals, organic matter and the like, thereby realizing purification of the raw water, so that the pure water flowing out of the wall-mounted water purifier 100 can meet the use requirements of drinking water.

[0038] Finally, the post-filter 16 is used to further finely filter the pure water, improve the taste and odor of the water, remove the trace of pollutants possibly left in the reverse osmosis process, obtain the required drinking water, and output the drinking water through the pure water outlet end. It should be noted that the pre-filter 11 and the post-filter 16 are integrated to form a composite filter 5 in the present application. The pre-filter 11 and the post-filter 16 can have various structures, which can be selected according to the purification requirements, and the present application does not limit the structures.

[0039] The raw water flowing into the raw water inlet end 1 is preliminarily filtered by the pre-filter 11, and then flows into the booster pump 13 through the water inlet electromagnetic valve 12. After being pressurized by the booster pump 13, the raw water is output to the reverse osmosis filter 14 connected to the booster pump 13. The raw water is purified by the reverse osmosis filter 14 to obtain pure water, and then the pure water is further filtered by the post-filter 16 and output to the pure water outlet end 2, so as to realize flexible control of the purification path and accurate management of the one-way flow.

[0040] The waterway system 10 further comprises a bypass unit 17, the bypass unit 17 comprising a bypass pipeline 171 and a bypass switch 172, a bypass inlet end 1711 of the bypass pipeline 171 being connected between the pre-filter element 11 and the water inlet electromagnetic valve 12, a bypass outlet end 1712 of the bypass pipeline 171 being connected between the pure water outlet 141 of the reverse osmosis filter element 14 and the post-filter element 16, and the bypass switch 172 being installed on the bypass pipeline 171 and used to control the conduction or blockage of the bypass inlet end 1711 and the bypass outlet end 1712.

[0041] Through the arrangement of the bypass unit 17, under normal circumstances, the bypass switch 172 controls the bypass inlet end 1711 and the bypass outlet end 1712 of the bypass pipeline 171 to be blocked, and the raw water of the raw water inlet end 1 can enter the reverse osmosis filter element 14 through the pre-filter element 11 and the water inlet electromagnetic valve 12 in sequence, and the pure water obtained through purification by the reverse osmosis filter element 14 can flow out from the pure water outlet 141 of the reverse osmosis filter element 14 to the pure water outlet end 2 through the post-filter element 16, thereby meeting the drinking water demand of the user under normal circumstances; in the event of a fault or power failure of the wall-mounted water purifier 100, the water inlet electromagnetic valve 12 is closed, and the bypass switch 172 controls the bypass inlet end 1711 and the bypass outlet end 1712 of the bypass pipeline 171 to be conducted, so that the raw water of the raw water inlet end 1 can be directly introduced into the bypass inlet end 1711 after being preliminarily filtered by the pre-filter element 11, and then flow out from the bypass outlet end 1712, and further filtered by the post-filter element 16 to flow out to the pure water outlet 141 of the pure water outlet end 2, so that the user can still obtain water source through the wall-mounted water purifier 100 in the event of a special situation, thereby meeting the emergency water demand of the user.

[0042] Optionally, the bypass switch 172 is one of a ball valve, a butterfly valve, a gate valve and a stop valve. The bypass switch 172 opened manually can avoid the failure of the bypass switch 172 caused by an emergency such as power failure, improve the reliability of the bypass switch 172, and thus effectively open the bypass pipeline 171 to supply water through the bypass switch 172 in the event of a fault or power failure of the wall-mounted water purifier 100, thereby meeting the emergency water demand of the user.

[0043] In an optional embodiment, the waterway system 10 further comprises a regulating valve 18, which is arranged between the booster pump 13 and the post-filter 16 and is arranged in parallel with the reverse osmosis filter 14. The arrangement of the regulating valve 18 enables the water pressurized by the booster pump 13 to partially flow out to the first check valve 15 through the regulating valve 18, and the other part of the water to flow out to the first check valve 15 after being purified into pure water by the reverse osmosis filter 14, so that the water flowing out through the regulating valve 18 and the pure water purified by the reverse osmosis filter 14 can be mixed to form mixed water flowing out to the post-filter 16. By adjusting the amount of water entering the reverse osmosis filter 14 from the booster pump 13 through the regulating valve 18, mixed water with different total dissolved solids (TDS) can be obtained, so that the TDS value of the mixed water can be adjusted through the regulating valve 18 to meet the water quality requirements in different scenarios.

[0044] To facilitate the mixing of the water flowing out through the regulating valve 18 and the pure water purified by the reverse osmosis filter 14, the waterway system 10 has a mixed water flow channel 4, and the regulating valve 18 and the pure water outlet 141 of the reverse osmosis filter 14 are both connected to the upstream of the mixed water flow channel 4, so that the water flowing out through the regulating valve 18 and the pure water purified by the reverse osmosis filter 14 can be mixed in the mixed water flow channel 4 to form mixed water.

[0045] In an optional embodiment, the waterway system 10 further comprises a first check valve 15 and a water storage bucket 197 for storing mixed water. The water storage bucket 197 is arranged between the upstream of the mixed water flow channel 4 and the first check valve 15, so that part of the mixed water in the mixed water flow channel 4 can enter the water storage bucket 197. By storing a certain amount of purified water in the water storage bucket 197, the user can take the water at any time, and the water storage bucket 197 can provide stable water outlet pressure, so that the user can use the mixed water more stably and continuously, and the use experience is better.

[0046] The first check valve 15 is arranged between the bypass water outlet end 1711 and the downstream of the mixed water flow channel 4. Through the arrangement of the first check valve 15, part of the mixed water in the mixed water flow channel 4 can stably flow to the post-filter 16 through the first check valve 15, so as to realize the stable distribution of the mixed water in the mixed water flow channel 4.

[0047] Further, the waterway system 10 further comprises a first detection member 190 arranged between the water inlet electromagnetic valve 12 and the booster pump 13, and the first detection member 190 is used to detect the TDS value of the water flowing out through the pre-filter 11.

[0048] Further, to obtain the TDS value of the mixed water, the waterway system 10 further comprises a second detection member 191 arranged on the mixed water flow channel 4, and the second detection member 191 is used to detect the TDS value of the mixed water.

[0049] Optionally, the regulating valve 18 is an electrically controlled regulating valve 18, and the working state of the regulating valve 18 is associated with the first detection member 190 and the second detection member 191, so that the working state of the regulating valve 18 can be adjusted based on the measurement results of the first detection member 190 and the second detection member 191, thereby controlling and adjusting the total dissolved solids of the outflowing mixed water to meet different water quality requirements.

[0050] In an optional embodiment, the waterway system 10 further comprises a pressure detection member 192, which is arranged between the raw water inlet end 1 and the pre-filter cartridge 11, and through which the pressure of the raw water entering the pre-filter cartridge 11 from the raw water inlet end 1 can be detected, so that the raw water with a pressure lower than a preset pressure enters the pre-filter cartridge 11, thereby avoiding damage to the pre-filter cartridge 11 caused by excessive water pressure. Optionally, the pressure detection member 192 can be a pressure valve, an electrically controlled pressure switch, or a pressure sensor.

[0051] In an optional embodiment, the waterway system 10 further comprises a second one-way valve 193, which is arranged between the pure water outlet 141 of the reverse osmosis filter cartridge 14 and the upstream of the mixed water flow channel 4, and the second one-way valve 193 is arranged in parallel with the regulating valve 18, and through which the purified pure water from the reverse osmosis filter cartridge 14 can be stably discharged into the mixed water flow channel 4.

[0052] The arrangement of the second one-way valve 193 can limit the flow direction of the pure water, so that the direction from the pure water outlet 141 of the reverse osmosis filter cartridge 14 to the upstream of the mixed water flow channel 4 is unidirectionally communicated, so that a unidirectional purified water path is formed between the water inlet electromagnetic valve 12, the booster pump 13, the reverse osmosis filter cartridge 14, and the second one-way valve 193. At the same time, in the process of conveying the raw water through the bypass pipeline 171, the second one-way valve 193 can effectively avoid the raw water from flowing back to the reverse osmosis filter cartridge 14 in cooperation with the first one-way valve 15, thereby reducing the possibility of damage to the reverse osmosis filter cartridge 14 caused by the backflow of the raw water in the bypass pipeline 171 to the reverse osmosis filter cartridge 14.

[0053] In order to control the discharge of the waste water generated by the reverse osmosis filter cartridge 14, the waterway system 10 further comprises a waste water electromagnetic valve 194, which is arranged between the waste water outlet 142 of the reverse osmosis filter cartridge 14 and the waste water outlet end 3, and through the opening and closing of the waste water electromagnetic valve 194, the discharge of the waste water generated by the reverse osmosis filter cartridge 14 to the waste water outlet end 3 can be controlled.

[0054] In an optional embodiment, the waterway system 10 further comprises a high-pressure switch 196, which is a protection element of the waterway system 10, and is arranged on the flow channel between the first check valve 15 and the post-filter 16. When the water pressure is too high, the high-pressure switch 196 can stop the operation of the waterway system 10 in time, so as to reduce the risk of damage to the waterway system 10 caused by excessive water pressure.

[0055] In an optional embodiment, the waterway system 10 further comprises a flow meter 195, which is arranged between the water inlet electromagnetic valve 12 and the booster pump 13, and is used to measure the water flow entering the booster pump 13.

[0056] Specifically, in the waterway system 10 of the present application, under normal circumstances, the bypass switch 172 blocks the connection between the bypass water inlet end 1711 and the bypass water outlet end 1712, raw water enters the pressure detection element 192 from the raw water inlet end 1, is detected by the pressure detection element 192, and then enters the pre-filter 11, is filtered by the pre-filter 11, enters the booster pump 13 through the water inlet electromagnetic valve 12 and the flow meter 195, and the TDS value of the water filtered by the pre-filter 11 is detected by the first detection element 190 before entering the booster pump 13. The water is pressurized by the booster pump 13, part of the water is sent to the reverse osmosis filter 14, the purified water purified by the reverse osmosis filter 14 flows out to the mixed water flow channel 4 through the second check valve 193, and the waste water generated by the reverse osmosis filter 14 is output to the waste water outlet end 3 through the waste water electromagnetic valve 194. Part of the water flows out to the mixed water flow channel 4 through the adjusting valve 18, and the purified water purified by the reverse osmosis filter 14 and the water flowing out of the adjusting valve 18 are mixed in the mixed water flow channel 4. The TDS value of the mixed water is detected by the second detection element 191, and the opening of the adjusting valve 18 is adjusted to obtain mixed water meeting the requirements. Part of the mixed water in the mixed water flow channel 4 enters the water storage barrel 197 for storage, and part of the mixed water in the mixed water flow channel 4 is sent to the post-filter 16 through the first check valve 15, is further filtered by the post-filter 16, and then flows out from the purified water outlet end 2 to meet the normal water demand of the user.

[0057] In special circumstances such as failure or power failure of the wall-mounted water purifier 100, the water inlet electromagnetic valve 12 is in a closed state, the bypass switch 172 makes the bypass water inlet end 1711 and the bypass water outlet end 1712 conductive, raw water enters the pre-filter 11 from the raw water inlet end 1, is filtered by the pre-filter 11, enters the post-filter 16 through the bypass pipeline 171, is further filtered by the post-filter 16, and then flows out from the purified water outlet end 2 to meet the emergency water demand of the user.

[0058] Generally, the elements of the waterway system 10 can be connected in sequence through pipes to realize the process of water delivery and transmission. In order to realize the integrated arrangement of the wall-mounted water purifier 100, the wall-mounted water purifier 100 in the present application further comprises an integrated waterway plate 30, and the elements in the waterway system 10 can be integrally installed on the integrated waterway plate 30, which helps to reduce the occupied area of the waterway system 10, and thus realize the compact design of the wall-mounted water purifier 100. It should be noted that the integrated waterway plate 30 is a preferred embodiment, and in other embodiments, the elements of the waterway system 10 can also be installed and connected through pipes.

[0059] Specifically, the integrated waterway plate 30 is provided with a raw water inlet 33, a pure water outlet 34 and a waste water outlet 35 on the circumferential side. The raw water inlet 33 is connected with an external water source to introduce raw water into the wall-mounted water purifier 100, and at this time, the raw water inlet 33 can serve as a raw water inlet end 1. The pure water outlet 34 is connected with a delivery pipe to discharge pure water that meets the drinking requirements after being purified by the waterway system 10 from the wall-mounted water purifier 100, and at this time, the pure water outlet 34 can serve as a pure water outlet end 2. The waste water outlet 35 is connected with a recovery pipe to discharge waste water that does not meet the drinking requirements generated by the waterway system 10 from the wall-mounted water purifier 100.

[0060] Further, the integrated waterway plate 30 forms a flow channel not shown in the drawings, and the elements in the waterway system 10 in the above embodiments are connected through the flow channel of the integrated waterway plate 30.

[0061] The pre-filter 11, the water inlet electromagnetic valve 12, the booster pump 13, the reverse osmosis filter 14, the first one-way valve 15, the post-filter 16 and the bypass unit 17 are all installed on the integrated waterway plate 30, so as to realize the filtration and purification of raw water into pure water under normal circumstances and the delivery of raw water through the bypass unit 17 in emergency.
